Atopic Dermatitis
Atopic dermatitis (also known as atopic eczema) is a disorder characterized by inflammation of the skin (dermatitis). The condition usually begins in early infancy, and it often disappears before adolescence. However, in some affected individuals the condition continues into adulthood; in others, it does not begin until adulthood. Hallmarks of atopic dermatitis include dry, itchy skin and red rashes that come and go. The rashes can occur on any part of the body, although the pattern tends to be different at different ages. In affected infants, the rashes commonly occur on the face, scalp, hands, and feet. In children, the rashes are usually found in the bend of the elbows and knees and on the front of the neck. In adolescents and adults, the rashes typically occur on the wrists, ankles, and eyelids in addition to the bend of the elbows and knees. Scratching the itchy skin can lead to oozing and crusting of the rashes and thickening and hardening (lichenification) of the skin. The itchiness can be so severe as to disturb sleep and impair a person's quality of life.

Non-alcoholic Fatty Liver Disease
Non-alcoholic fatty liver disease (NAFLD) is a buildup of excessive fat in the liver that can lead to liver damage resembling the damage caused by alcohol abuse, but that occurs in people who do not drink heavily. The liver is a part of the digestive system that helps break down food, store energy, and remove waste products, including toxins. The liver normally contains some fat; an individual is considered to have a fatty liver (hepatic steatosis) if the liver contains more than 5 to 10 percent fat.

European Mink Mustela lutreola L.,1761
European mink Mustela lutreola L., 1761 is considered one of the most endangered mammalian species in the world, due to its ongoing population depletion, both in terms of the actual number of individuals and area occupied. The species was originally spread over most of continental Europe, but nowadays only three wild, isolated, declining populations occupying less than 3% of the former range survive with only about 5000 individuals are estimated persisted in the wild. The alarming situation of the species is proven by its categorization as critically endangered (CR) by the International Union for Conservation of Nature (IUCN) Red List of Threatened Species, and it is listed in Annex II to the Bern Convention on the Conservation of European Wildlife and Natural Habitats, Annexes II and IV (priority species) of the Council Directive 92/43/EEC on the conservation of natural habitats and of wild fauna and flora, and in The Carpathian List of Endangered Species (critically endangered species (CR)). Despite this, studies in the field of genetics of M. lutreola are limited and urgently need to be completed, especially in the context of the progressing extinction process and the disappearance of its numerous populations in France, Belarus, and Russia, among others. The rapidly shrinking and vanishing genetic resources will largely never be studied and described, which is an irreversible loss from cognitive and practical points of view. The meagre data on interpopulation genetic diversity may significantly impair the efficacy of the implemented activities for restitution of the European mink, especially in the context of conservation breeding and species reintroduction. Notably, only (conservation) genetics can provide tools to rescue species affected by the extinction vortex, which, in turn, requires more research initiatives in the conservation genetics of the European mink.

TERT Expression Regulation by Epigenetics
Maintenance of telomeres is a fundamental step in human carcinogenesis and is primarily regulated by telomerase and the human telomerase reverse transcriptase gene (TERT). Improved understanding of the transcriptional control of this gene may provide potential therapeutic targets. Epigenetic modifications are a prominent mechanism to control telomerase activity and regulation of the TERT gene.

Cohen Syndrome
Cohen syndrome is an inherited disorder that affects many parts of the body and is characterized by developmental delay, intellectual disability, small head size (microcephaly), and weak muscle tone (hypotonia). Other features common in this condition include worsening nearsightedness (myopia), breakdown (degeneration) of the light-sensitive tissue at the back of the eye (retinal dystrophy), an unusually large range of joint movement (hypermobility), and distinctive facial features. These facial features typically include thick hair and eyebrows, long eyelashes, unusually-shaped eyes (down-slanting and wave-shaped), a bulbous nasal tip, a smooth or shortened area between the nose and the upper lip (philtrum), and prominent upper central teeth. The combination of the last two facial features results in an open mouth.

Genetic Improvement of Drought Tolerance in Conifers
The constant rise in the global temperature and unpredictable shifts in precipitation patterns are two of the main effects of climate change. Conifers originated more than 300 million years ago and currently dominate many temperate and boreal forests.

CRISPR/Cas9-Based Genome Editing on Abiotic Stress Tolerance
Plants are subjected to various environmental stresses that negatively impact growth and development and limit crop productivity. Therefore, in order to meet the requirements of the growing world population and food security, it is essential to develop cultivars resistant to abiotic stresses. In recent years, with the availability of genetic databases and the advancement in genome editing techniques, it is feasible to edit target genes with precision and create new opportunities for crop improvement that conventional breeding methods could not achieve. The genome-editing method using CRISPR-Cas systems is very powerful and confers exceptional versatility to develop improved cultivars at abiotic stresses. These efficient gene editing techniques facilitate the cultivation of superior-performing genotypes in challenging environmental conditions without compromising yield.

LncRNA in Colorectal Cancer
Colorectal cancer is the third most common cause of cancer mortality worldwide, and one of the current hot topics in this field is the identification of markers for identifying patients with high probability of relapse, which may benefit from adjuvant chemotherapy in stage II. In this sense long noncoding RNAs are a promising source of novel cancer biomarkers and therapeutic targets, although to robustly assess their gene expression levels is challenging due to their low expression. We present a protocol (hereafter referred as CoLong design) which couples target enrichment and RNA-seq that allows transcriptomics studies of lncRNAs in formalin-fixed paraffin embedded (FFPE) tissue samples. We show that our new approach alllows to efficiently detect differences in gene expression and somatic mutations in lncRNAs, and we propose several lncRNAs as potential candidates for colorectal cancer. This new approach could represent a promising avenue that would reduce costs and enable more efficient translational research.

Björnstad Syndrome
Björnstad syndrome is a rare disorder characterized by abnormal hair and hearing problems. Affected individuals have a condition known as pili torti, which means "twisted hair," so named because the strands appear twisted when viewed under a microscope. The hair is brittle and breaks easily, leading to short hair that grows slowly. In Björnstad syndrome, pili torti usually affects only the hair on the head; eyebrows, eyelashes, and hair on other parts of the body are normal. The proportion of hairs affected and the severity of brittleness and breakage can vary. This hair abnormality commonly begins before the age of 2. It may become milder with age, particularly after puberty.
